You can buy a cheap pda which will do all this and more for not much money.

If you do want to go ahead with this, then you could investigate the platforms that PDA's, Sat navs and mobile phones use.

i think pda is too expensive. it's cost above $250. And i want may device to be sold around $200 or maybe less.

any solution?
